It outputs a ratiometric voltage proportional to the sensed current, with a sensitivity of 400 mV/A. The sensor is AEC-Q100 qualified for automotive applications and operates over the full -40°C to 125°C temperature range, making it suitable for under-hood and industrial environments where reliability is critical. ## Key ratings and what they mean for your BOM The ±5.75 A sensing range covers many automotive loads — motor windings, solenoid drivers, or battery-monitoring paths. The 400 mV/A sensitivity gives a 2.3 V full-scale output at 5.75 A with a 5 V supply, which maps cleanly into a 3.3 V or 5 V ADC input without external scaling. The 80 kHz bandwidth supports control loops and overcurrent detection with a 6.5 µs response time, fast enough for most motor-drive and power-converter fault responses. Ratiometric output means the output voltage scales with the supply voltage (4.5 V to 5.5 V), so the measurement accuracy holds even if the supply drifts — useful in automotive environments where the 5 V rail may sag during cranking. The ±0.05% linearity ensures the transfer curve stays tight across the full range, reducing the need for multi-point calibration in production. Supply current max is 6 mA, so the sensor adds negligible load to the 5 V rail. The single-channel, surface-mount 8-SOIC footprint is straightforward for hand-soldering or reflow, and the package is narrow (3.90 mm width), saving board space compared to larger through-hole Hall sensors. ## Automotive qualification and sourcing posture The TMCS1101A4BQDRQ1 carries AEC-Q100 qualification, which means it has passed the stress tests required for automotive-grade components — extended temperature cycling, high-temperature operating life, and ESD robustness. This qualification also makes it a natural fit for industrial and telecom designs that demand similar reliability margins. Lifecycle status is active per the manufacturer, so there is no end-of-life risk for new designs or ongoing production. The part is available through independent distribution and is quoted to order against an RFQ — current pricing and availability are confirmed at the time of quotation.","metaTitle":"TMCS1101A4BQDRQ1 Hall-Effect Current Sensor, ±5.75A, 400mV/A","metaDescription":"Automotive-grade Hall-effect current sensor by TI.
